HYnRocAR-Bon BURNER.

Application filed December 11,'19722. Serial No. 606,G92.

To all whom t may concern Be it known that I, Monnrs B. MOSER, a citizen of the United States, residing at l/Vells, in the county of Faribault and State of Minnesota, have invented certain new and useful Improvements in Hydrocarbon Burners; and 1 do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention provides a simple and highly efficient hydro-carbon burner which is adapted to burn not only the intermediate grades such as kerosene .and distillate, but also much lower grades of oil such as crude oil or even worn out' lubricating oils.

Generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.`

The improved burner hereinafter described may, of course, be made in various different sizes and it is adapted `for application in furnaces, boilers, heating stoves, cooking stoves and the like. Then applied inlarge fire pots such as that of furnaces and boilers, a plurality or group of individual burners will preferably be applied in order that a very large range of variation in heating capacity may be taken care of by making the individua-l burners of different sizes.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings:

Fig. 1 is a plan view showing the improved burner;

Fig. 2 is a vertical sectiontaken on the line 2-2 of Fig. 1; y

Fig. 3 is a side elevation of the burner, the lower portion thereof being" broken away; .Y

Fig. 4 is a plan view of the burner with the deflect-ing cap of the burner removed; and

Fig. 5 is a plan view of the burner with both' the deflecting cap and the stack cap removed, and with some parts sectioned.

The burner comprises a central air intake stack 6 preferably made up of sections telescopically connected at 7. The lower stack section 6 is shown as formed integral with a surrounding annular priming pan 8 from the bottom of which a drain pipe 9 is exat the upper end of the stack, auxiliary air discharge stack. Y

The numeral 15 indicates a stack cap of ports le are provided in said inverted cup-shape form, the depending flange of which is ciroumferentially spaced around and from the upper end of the stack. The fuel pipe 11r is passed through a central axial passage in thecap 15, and the said cap is held in operative position` shown in the drawings by be'aring'lugs 16 on Vthe extreme upper end of the stack.

Located above and extending around the stack cap 15 is a deflecting cap 17 provided at its center with a raised hub 18 into which the delivery end ofthe fuel pipe 11 is eX- tended with clearance. Preferably, the upper end of the fuel pipe 11 is threaded not for the purpose of engagement with the de.- flecting cap but to afford a plurality of fine lribs around the delivery end of the fuel pipe which. will 1retard'the downward flow of the oil.

The depending peripheral flange of the deflecting'cap 17 'for different purposes will be diierently designed, but in the preferred arrangement it is provided with a relatively shallow depending flange 19 that extends through approximately '180 and with which deeper depending flange 2O that extends through. the other 180 of the circumference of said cap. The flange 19 is terminated above the lower'edg'e of the flange of the stack cap 15 while the lower edge of the `liange 2() extends nearly or quite into contact with the deflecting iiange 10 of the stack. rllhehub 18 of the deflecting cap is shown as provided with knob or handle 21 which permits the deflecting cap to be readily given rotary adjustments around the axis of the stack and fuel pipe 11. The stack cap 15 is provided with a shallow upstanding annular flange 22 upon which the deflecting cap loosely rests, Vand to facilitate the radial discharge of oil or fuel vapor, the said flange is provided with notches 23.

Operation.

When the burner is started into action for the first time, a priming charge of gasoline should be placed in the priming pan 8 and ignited so as to heatthe metallic partsof the burner to quite a high temperature and thena supply of oil or hydro-carbon fluid lshould be turned on through the pipe 11.r

' time the space between the two caps 15 Vand 17 will be filled up with carbon, but this Y carbon will be of a porous or spongyY char* acter` capable of absorbing and holding a considerable' amount of oil or hydro-carbon fluid. This filling in of the said space with the'carbon product is just what isdesired for it is then utilized as a sort of wick, and thereafter in starting the burner, priming is not necessary, but it is only necessary to turn on the fuel supply and tol ignite the oil at the exposed surface of the carbon deposit. VVhe'n thus first starting the burner` into action, the fuel will burn as oil, but the heat of combustion will soon make the metallic parts of the burner and the carbon deposithot so that the rfuel will be delivered to the air in the form of vapor. When the burner is inaction after the carbon deposit has been formed there will be a very even distribution of the fuel vapor at the exposed surface of the carbon deposit. The air .will be drawn from the burner radially outward and upward. With the deep semicircular flange 20, the flame projected fromV theburner will bev semi-circular andY will project on'thatL side that is away rfrom the Y deep flange 20. Byincreasing lor decreasing Vthe circumferential.extent of flange 2O the circumferential extent Of the flame may be increased or decreased in reverse order and,

of course, if the entire depending flange of cap 17 be of a consistent depth such as that l of the flange 19, then there will be produced a circular or annular radially and ups..

wardly projected flame. The edge of the deep segmental flange 2O may project where it will produce the greatest heating effect within the fire combustion within which it is applied. For instance, the cap may be adjusted so that all of the flame will be projected toward 0r against an adjacent wall Vof the fire pot or heater.V This is especially important where individual burners are arranged in groups within the saine fire pot or combustion chamber.

When the carbon deposit has been formed it will be 'self-maintaining, that is: surplus carbon at the exterior will be burned away and the interior deposit will be maintained up to a point where the space'intervening between the two caps will be filled with the porous or sponge-like carbon deposit.

It will, of course, be understood that such a carbon deposit will absorb and hold very considerable amount of oil or fuel, and'that as further oil supply is cut off from the fuel pipe V11 Vthere will be a flamecontinued for aV considerable time but graduallydiminish- `ing in intensity to a pointV where it goes out,

and in lightingVV the burner there will be a flame gradually increasing in intensity up to a point of maximum intensity. Of course, the customary pilot light may be provided if desired, and hence the burner, even whenintermittently operated, will'give much` more nearly the eectY of a flame progressively varied in intensity to the heat rer quiiyement, than is the burner that goes coni.-

pletely on and completely off with the Substantially instantaneous action. The statements above made are based on a long and continued actual use of the burner described.Y

What I claim is: i

1. A hydro-carbon burner eomprisin(T an air intake stack, a stack cap spaced a ove and surrounding the upper end of said stack,

o f a deflecting cap located above said stack cap, and a fuel feed pipe extended upward through said stack and stack cap and de# livering into the deflecting cap, said stack below saidcap having an outstanding deflecting flange and said deflecting cap having a depending flangel which, throughout a portion of a circle, terminates high above the deflectingflange of said stack and which throughouty the reniaininglportion of the circle. extends downward substantially to said deflecting flange.

2. The structureY defined in claim 1 in uohich the deflecting cap is rotatably adjusta le. v

In testimony whereof I aflix my signature.
